Specification of Letters Patent. Application filed April 18.1905.l Serial No. 256,279.

Patented Nov. 6, 1906.

mouthpiece or beam is made to slide up and down vthe cross-bars of the cheeks within certain limits, said cross-bars having stops above and below the mouthpiece to limit the movements of the same. v

This invention consists of the herein-described improvements in the construction of the side cheeks so that the ends of the beam or mouthpiece can be made solid instead of being made, as is usual, with jaws which are closed round the cross-bars of the cheeks, s as to slide upon the same.

I will describe my invention by referring to the accompanying drawings, on which-' Figure 1 is a front elevation, partly in section, of a bridle-bit constructed in accordance with this invention. Fig. -2 is a side elevation of the main portion of one of the ins/o side cheeks of the said bit sufiicient to illustrate my invention. Fig. 3 is a sectional side elevation of a portion of one of the side cheeks of the said bit before being attached to the mouthpiece. Fig. 4 is a side elevation, and Fig. 5 is a front elevation, of a pin art of one of the said'side cheeks of the ridle-bit. Fig. 6 is a lan of said pin. Fig. 7 is a side elevation o a portion of the said pin. Fig. 8 is a sectional side elevation and plan of a portion of the cross-bar of one ofthe side cheeks of the said` bit on which the themout'hpiece works. Fig. 8X is a sectional elevation and sectional plan of a modified -form of said cross-bar for the same cheeks. Fig. 9' is a front elevation, partly in section, of oneof the cheeks of a bridle-bit and a portion of the mouthpiece to illustrate a further modification of my invention. v Fig. 10 is a -sectional plan of the same on line of Fig.-

9. Fig. 11 is a side elevationl of .fthe-.same cheek looking from the inner side ofthe bit, this view also showing the mouthpiece in section. Fig. 12 is a sectional planof the same on line Y Y of Fig. 11. Fig.13 is a front elevation of thecross-barportion ofthe side cheek shown in Figs. 9, 10, 11, and 12. Fig. 14 is a side elevation of the same cross-bar, and Fig. 15 is a plan of the same. Fig. 16 is a side elevation, partly in section, of the main portion of one of the side cheeks of the.

said bit, illustrating a slight modification of the arrangement shown by Figs. 1, 2, and 3. Fig. 17 shows thesame side cheek as Fig. 16 before the cross-bar and mouthpiece are connected thereto. Fig. 18 is a similar view to Fig. 16 to illustrate a further modification of my invention, and Fig. 19 shows thesame side cheek as Fig. 18 before the crossbar and mouthpiece are connected thereto.

The same reference-numerals indicate' the same or corresponding parts in all the figures. I will first describe the arrangement of my invention illustrated by Figs. 1 to 8, both inclusive. 1 is the mouthpieceof the bit, and 2 3 are the two side cheeks of the same.v In carrying out my invention the beam or mouthpiece 1 is made solid in one piece, with the eyes 4 5 at its ends to slide upon the crossbars of the cheeks 2 3, and in order `to enable the solid-ended beam 1 to be connected onto `the cross-bars of the cheeks 2- 3 these cross-l bars, of which there is one for each cheek, are,

together with the cheeks, constructed as I will now describe, and in order to simplify my description I will refer to only one cheekthat is, the cheek marked 2-and its crossbar, although it will be understood that the cheek3 and 4its cross-bar are similarly constructed. The side cheek 2 is iirst cast orl y otherwise formed with a gap 6, where the en d 4 of the beam or mouthpiece works, leaving two bosses 7 8 on the side cheek, which bosses 7 8 are in reality-portions of the cross-bar, one boss-vnamely, that marked 7-being above the gap 6 and the other boss 8 being below the gap. The part 9 of the cross-bar on which the end 4 of the beam or mouthpiece slides is made separately from the side cheek 2 in the form of a nickel or other suitable'non-rusting short metal tube 9, which is IOO shown separately by Fi .8 and which is made of the proper length to `t in between the two bosses 7 8 of the side cheek, as shown in Figs.

1 and 2. This tube 9 isthreaded through the eye 4 of the mouthpiece or beam 1 and secured in place in the gap 6 by ay solid vertical steel or other wire pin'lO, which is passed down a central hole 1 1 from the top of the said cheek through the tube 9 and across the gap 6 and into the lower boss 8 and is there secured it in the side cheek. Thus the mouthpiece or i by the cheek 2, being riveted over at the top of the pin 10 or by other suitable means, as by the pin 10 being made with two lateral depressions 18 19 on those parts which are inclosed in the bosses 7 8, so that when the pin 10 is in position in the hole 11, as in Figs. 1 and 2, the metal at the front of the bosses can be squeezed into these depressions 18 19,

as shown in Fig. 12, thereby effectually securing the pin 9 in position in the hole 1 1 and preventing the bosses 7 8 from springing apart in case the bit should be dropped on one of the bow parts 22 of the side cheek. When the pin 1() is made of steel, (and this -is preferable,) we place in the hole 11 on the beam 1 is effeetually secured to the side cheek 2, which latter is rendered very strong, as the steel or other metal pin 10 forms a strengthening-core for the same.

In the arrangement above described with reference to Figs.l 1 to 8, both inclusive, the tubular cross-bar 9 is circular in plan, and the eye 4 in the end of the mouthpiece or beam 1 1s made of corresponding shape and size to iit onto the tubular cross-bar 9, but it is to be understood that when applying my invention to those bits in which the cross-bars of the cheeks and the eyes of the mouthpiece are made square to prevent the side cheeks from turning then I make the tubular crossbar square on the outside, as shown in Figs. 9 to 15, both inclusive, in which it will be seen that the tubular cross bar in this case (marked 13) is made square in plan, and the eye 4 in the end of the mouthpiece or beam 1 is also made square to iit on this square crossbar 13. In order to prevent the square cross-bar from turning on the pin 10, the ends 14 15 of the said cross-bar are, by preference, made inclined as shown and fitted in inclined slots 16 17', formed in the ends of the bosses 7 8,as shown in Figs. 9, 10, 11, and 12.`

ForI additional security the ends of the short metal tube 9 may, if desired, be sunk into recesses, such as 20 21, in the ends ofthe bosses 7 8 of the side cheek, and in this case in order to get the cross-bar 9 in position the bow parts 22 of the side cheek, which connect the upper and lower parts of the side cheek together, have to be somewhat attened, as in Fig. 17, thereby extending the length of the gap 6, so that the short tube 9 can readily be placed in position, and then when this has been done the bosses are forced toward each other again, so that the ends of the tube 9 will iit in the recesses 21 22, and this is done by driving a drift into the bow parts 22, so as to bend the same outwardly to their normal shape, (shown in Fig. 16,) which has the eil ect of bringing the bosses 7 8 nearer together and gripping the tubular cross-bar 9 between them.

When the tubular or solid cross-bar 9 is fixed in position between the bosses 7 8 by its ends iitting in recesses 20 21, as last described and illustrated by Figs. 16 and 17, then the wire or other pin 10 can, if desired, be dispensed with; but we prefer to use the said pin, as shown in Fig. 16, and to provide it with the indentations 18 1.9 and to force the substance of the metal of the bosses 7 8 into these indentations, as above described, so as to prevent the bosses 7 8 from separating farther apart in the event of the side cheek being dropped on one of the bow parts 22, as stated above.

In a further modiiication of this invention (see Figs. 18 and 19) the two bosses 7 8 are formed with short pins 23 24, which project axially from the centers of the bosses 7 8 and take into the holes in the ends of the tubular or other filling-up piece 9, as shown in Fig. 18, which lilling-up piece is placed in position by first extending the distance between the bosses 7 8, which is done by squeezing the bow parts 22 toward each other, as stated above, or by casting the side cheek with these bow parts nearer together than in the finished bit, as shown in Fig. 19, and then when the tubular cross-bar 9 is placed in position to engage with the pegs 23 24 the bosses 7 8 are forced together again, so that their pins 23 24 engage in the ends of the 'lilling-up piece or cross-bar 9 and hold the same in position with the eye 4 of the mou thpieee or beam threaded thereon, as shown by Fig. 18.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A bridle-bit comprising a mouthpiece having an eye at each end, two side cheeks, each composed of a circular portion and two hollow bosses extending inwardly from the circular portion, said bosses being dialnetrically opposite each other and leaving a gap between their free ends, two tubes passing through the eyes in the mouthpiece and 'lilling the gaps in the side cheeks and bars passing through said tubes and having their ends held in the hollow bosses.
